Hidden deals at Costco and Sam's Club: Cars, insurance, mortgages

Warehouse stores like Costco and Sam's Club sell almost everything in bulk, from diapers to detergent. Now, they have made a big jump to help you cover financial areas of your life as well.

Running through a warehouse store, you can find just about anything. Chris McGlothan loves trying to get a deal at Sam's Club.

"You know family, friends are always coming over to the house a lot," McGlothan said while standing in front of a cart filled with groceries. "We grill a lot. So, we like to do big things in big bulks."

New Cars

But among the big screen TVs and big four-wheel ATVs, there are also even bigger wheels. You can now buy cars through Costco at a predetermined price through local dealerships.

"So there's not a lot of haggling," said Mike Gibson, Costco warehouse manager. "You kind of see it's black and white, what you're going to pay for the vehicle."
